== EXAMPLE
|
|
|
|
=== GET FORM VALUES
|
|
|
|
require "cgi"
|
|
cgi = CGI.new
|
|
values = cgi['field_name'] # <== array of 'field_name'
|
|
# if not 'field_name' included, then return [].
|
|
fields = cgi.keys # <== array of field names
|
|
|
|
# returns true if form has 'field_name'
|
|
cgi.has_key?('field_name')
|
|
cgi.has_key?('field_name')
|
|
cgi.include?('field_name')
|
|
|
|
|
|
=== GET FORM VALUES AS HASH
|
|
|
|
require "cgi"
|
|
cgi = CGI.new
|
|
params = cgi.params
|
|
|
|
cgi.params is a hash.
|
|
|
|
cgi.params['new_field_name'] = ["value"] # add new param
|
|
cgi.params['field_name'] = ["new_value"] # change value
|
|
cgi.params.delete('field_name') # delete param
|
|
cgi.params.clear # delete all params
|
|
|
|
|
|
=== SAVE FORM VALUES TO FILE
|
|
|
|
require "pstore"
|
|
db = PStore.new("query.db")
|
|
db.transaction do
|
|
db["params"] = cgi.params
|
|
end
|
|
|
|
|
|
=== RESTORE FORM VALUES FROM FILE
|
|
|
|
require "pstore"
|
|
db = PStore.new("query.db")
|
|
db.transaction do
|
|
cgi.params = db["params"]
|
|
end
|
|
|
|
|
|
=== GET MULTIPART FORM VALUES
|
|
|
|
require "cgi"
|
|
cgi = CGI.new
|
|
values = cgi['field_name'] # <== array of 'field_name'
|
|
values[0].read # <== body of values[0]
|
|
values[0].local_path # <== path to local file of values[0]
|
|
values[0].original_filename # <== original filename of values[0]
|
|
values[0].content_type # <== content_type of values[0]
|
|
|
|
and values[0] has Tempfile class methods.
|
|
(Tempfile class object has File class methods)
|
|
|
|
|
|
=== GET COOKIE VALUES
|
|
|
|
require "cgi"
|
|
cgi = CGI.new
|
|
values = cgi.cookies['name'] # <== array of 'name'
|
|
# if not 'name' included, then return [].
|
|
names = cgi.cookies.keys # <== array of cookie names
|
|
|
|
and cgi.cookies is a hash.
|
|
|
|
|
|
=== GET COOKIE OBJECTS
|
|
|
|
require "cgi"
|
|
cgi = CGI.new
|
|
for name, cookie in cgi.cookies
|
|
cookie.expires = Time.now + 30
|
|
end
|
|
cgi.out("cookie" => cgi.cookies){"string"}
|
|
|
|
cgi.cookies # { "name1" => cookie1, "name2" => cookie2, ... }
|
|
|
|
require "cgi"
|
|
cgi = CGI.new
|
|
cgi.cookies['name'].expires = Time.now + 30
|
|
cgi.out("cookie" => cgi.cookies['name']){"string"}
|
|
|
|
and see MAKE COOKIE OBJECT.
|
|
|
|
|
|
=== GET ENVIRONMENT VALUE
|
|
|
|
require "cgi"
|
|
cgi = CGI.new
|
|
value = cgi.auth_type
|
|
# ENV["AUTH_TYPE"]
|
|
|
|

|
|
REMOTE_USER REQUEST_METHOD SCRIPT_NAME SERVER_NAME SERVER_PORT
|
|
SERVER_PROTOCOL SERVER_SOFTWARE
|
|
|
|
content_length and server_port return Integer. and the others return String.
|
|
|
|
and HTTP_COOKIE, HTTP_COOKIE2
|
|
|
|
value = cgi.raw_cookie
|
|
# ENV["HTTP_COOKIE"]
|
|
value = cgi.raw_cookie2
|
|
# ENV["HTTP_COOKIE2"]
|
|
|
|
and other HTTP_*
|
|
|
|
value = cgi.accept

|
# ENV["HTTP_ACCEPT"]
